Unable to Install git package on ubuntu 14.04

Question

So, I'm trying to install git on Ubuntu 14.04... When I typed:

sudo apt-get install git

It said:

E: Unable to locate package git

So after some time searching I ran:

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys E1DD270288B4E6030699E45FA1715D88E1DF1F24
sudo su -c "echo 'deb http://ppa.launchpad.net/git-core/ppa/ubuntu trusty main' > /etc/apt/sources.list.d/git.list"

sudo apt-get update 
sudo apt-get install git

and now I get this:

Reading package lists... Done
Building dependency tree
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable

The following packages have unmet dependencies:
 git : Depends: liberror-perl but it is not installable

       Recommends: rsync but it is not installable
       Recommends: ssh-client but it is not installable

What am I doing wrong? Can you help me someone? Thanks for your replys...
